The AirTAC SC50 Standard Cylinder SC50X500H is a genuine double-acting standard air cylinder with a Ø50mm bore and 500mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X500H is a double-acting pneumatic cylinder with a 50 mm bore and 500 mm stroke, built for high-temperature service with Viton (FKM) seals that extend the operating range to 0–150 °C. At 0.5 MPa it produces 982 N pushing force and 825 N pulling force, rising to 1767 N push at the 0.9 MPa maximum operating pressure, making it a solid mid-range actuator for thermal-process tasks.
This tie-rod cylinder uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, while the 150 mm body length plus stroke gives a compact extended envelope of 650 mm. The SC50X500H is a standard-stroke model within the 1200 mm maximum for bore 50.

Viton seals allow the SC50X500H to operate continuously in ambient temperatures up to 150 °C, making it suitable for actuators near ovens, autoclaves, or foundry mould-handling stations where standard seals would degrade.
With 1767 N of push force at 0.9 MPa, this cylinder provides the clamping pressure needed for hot-press laminating, composite curing, or thermal bonding fixtures, while the adjustable cushion protects tooling at the end of the 500 mm stroke.
The high-temperature FKM seal package makes the SC50X500H a reliable choice for automating large butterfly or gate valves on steam and hot-fluid lines in chemical plants, dairies, and sterilisation systems.
Choose the SC50X500H when you need a 50 mm bore cylinder that withstands ambient temperatures up to 150 °C. If your force requirement is lower, stepping down to the 40 mm bore (628 N push at 0.5 MPa) saves space; for heavier loads the 63 mm bore delivers 1559 N at the same pressure. The 500 mm stroke is well within the standard range, but for strokes of 300 mm and above, avoid unsupported side loads—the 20 mm rod can bend under lateral force. Use an external guide rail or switch to a guided cylinder if side loading is present.
For a direct replacement, match these five points exactly: 50 mm bore, 500 mm stroke, PT1/4 port thread, basic (no mounting accessory), and Viton seal material. The SC50X500H does not include a magnet; if you need barrel-mounted position sensors, order the -S magnet variant and add CMSG/DMSG sensors separately.
Quick checklist
At 0.5 MPa the cylinder delivers 982 N extending (push) and 825 N retracting (pull). At 0.7 MPa push force rises to 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes, the SC50X500H is dimensionally identical to the standard SC50X500—same 50 mm bore, 500 mm stroke, PT1/4 ports, and tie-rod body. The only difference is the Viton (FKM) seal material, which upgrades the temperature rating from -20–70 °C to 0–150 °C. Ensure your application actually requires high-temperature seals, as Viton has a higher minimum temperature (0 °C) than standard TPU.
